Soooo my guinea pig lost 10 grams he is 7 months old about and now he put it back on in a week (he lost it in a week) so thats not really the problem I'm pretty sure hes eating well hes breathing is fine and yadda yadda yadda, but theres a little crustiness or i dunnno if its crusty i havent like touched it but like some markish thing like in the corner of his eye..on yahoo answers they said it was respitory infection but hes eating fine and breathing fine, could he just have a dry eye or something any ideas? Just to ease my worrying
